ZagTrader Makes FIX Parser and MT/MX Parser Free Permanently With No Sign-Up

ZagTrader said on November 15, 2026 that its FIX Parser and Log Analyzer and its MT/MX Parser are free permanently, with no sign-up and no account. The Dubai-based capital markets software company announced the change in a release published by EIN Presswire.

What the Two ZagTrader Parsers Do

The FIX Parser and Log Analyzer, hosted at fixparser.zagtrader.com, decodes FIX 4.0 to 5.0 SP2 messages and logs tag by tag. It checks BodyLength and CheckSum, finds sequence gaps and follows each order from new to fill. Loaded with a whole log, it reports fill and reject rates, ack latency percentiles, reject reasons ranked by code and session health.

The FIX tool also offers a message builder, a side-by-side comparison of a client log and a broker log, a FIX dictionary for every version from 4.0 to 5.0 SP2, and troubleshooting pages for common session and order errors. A free HTTP API returns the same log statistics as JSON, HTML or text.

The MT/MX Parser at mt-mx-parser.zagtrader.com decodes Swift MT and ISO 20022 (MX) messages, including header blocks, every field with its name and decoded value, 16R/16S sequences, ISO 20022 element trees with element definitions, and format checks for BIC, IBAN, ISIN, LEI, UETR, dates and amounts. Its reference pages cover MT message types, ISO 20022 messages, settlement status and reason codes, corporate action events and the MT to ISO 20022 equivalents. Free checkers for IBAN, BIC, UETR, ISIN, CUSIP, SEDOL, FIGI and CFI codes and an LEI search sit beside it.

Both tools parse in the browser: messages and logs that users paste or open are not uploaded. Logs sent to the FIX log analysis API are processed in memory and not stored. The tools are built by the teams behind ZagTrader's FIX connectivity and Swift messaging, and documentation with API examples in shell, Python and JavaScript and a sample FIX log is published on GitHub at github.com/ZagTrader.

ZagTrader's Earlier Launches and Crypto.com Link

ZagTrader launched Build on ZagTrader in June 2026, enabling banks, brokers and fintechs to build branded trading experiences on its capital markets infrastructure, with APIs, webhooks and source code packaged for client use under commercial arrangements, EIN Presswire reported.

In July 2026, ZagTrader extended its Portfolio Management module with strategy drift monitoring and controlled rebalancing execution capabilities, Globalfintechseries reported. In September 2026, Crypto.com Exchange and ZagTrader established direct connectivity, adding Crypto.com as a trading destination on ZagFN and letting over 100 institutions with over $500 billion in assets access Crypto.com without system changes, Finbold reported.

Where the Free Tools Are Documented

ZagTrader publishes documentation for both tools, API examples in shell, Python and JavaScript and a sample FIX log on GitHub at github.com/ZagTrader. The company's own announcement names fixparser.zagtrader.com and mt-mx-parser.zagtrader.com as the addresses for the two tools.
